Thunderjaw has a tail now.
@Gabe Q like @Big s explained it's the Moderoid Thunderjaw from the game "Horizon Zero Dawn". The quality is great & it will keep you busy for some time.
Very nice interpretation of this kit; it's always interesting to see a familiar design in a new light.
It would look more realistic if you went a tad lighter on those heavily engraved panel lines IMO. The texture on the exhaust parts is cool.
